[Elecraft] K3: Noise reduction tutorial/primer available?

[Edward R Cole]

Don,

Thanks for the references.  Many of us were not on this reflector or 
even owned a K3 in 2009 so would not know.  I am printing this off 
for future reference when I am ready to investigate NR/NB more thoroughly.

There was "straight talk" about NR from Lyle Johnson (who designed and
implemented the algorithms) in his reflector posts of 8/25/09 and
8/27/09 as well as the information in the Firmware Release Notes for
version 3.30 (avaliable using the K3 Utility Help pulldown).
Page 25 of the K3 manual has a comprehensive description of the tools
available  - Reducing Interference and Noise section.
The manual content is Wayne's work, so those who know most about those
implementations have already spoken.
I am not certain how much more authoritative information you are seeking.
As far as explicit "Here is how you use it" - each individual case or
instance of noise is different and will require different treatment.
Each user will have to cycle through the settings available to see which
works best - the result is a compromise, there is little that can move a
signal out of the noise and provide a completely distortion-free and
clear copy signal - copy will be improved, but just how much is improved
and how much distortion is tolerable is a question each operator must
answer.
